LONDON, June 25, 2026 – After more than two years of consecutive declines, the cost of comprehensive motor insurance in the UK has finally ticked upward. Average premiums increased by 1%—or £8—to reach £719 for the three-month period ending in May, according to the latest data from the Confused.com Car Insurance Price Index and Willis Towers Watson (NASDAQ: WTW). The index, which draws on over 6 million quarterly quotes, marks the first quarterly rise since premiums peaked at £995 in December 2023.
While the modest increase may seem like a relief for insurers after nine straight quarters of falling prices, the underlying dynamics are far from straightforward. Premiums remain 5% lower than a year ago, translating to a £38 drop on an annual basis. However, the cost of claims and repairs continues to climb, creating a margin squeeze that investors in major UK motor insurers are watching closely.
Regional Disparities and Rising Claims Costs
The national average masks significant regional variation. Northern Ireland saw the sharpest increase, with premiums jumping 8%—or £73—to £1,020, the first time the region has breached the £1,000 mark since December 2023. In contrast, Inner London was the only region to record a decline, with premiums slipping 0.4% to £1,088. The West Midlands remained nearly flat, rising just 0.1% to £860.
These regional differences are critical for publicly traded insurers. A 1% national increase can obscure much larger swings in areas hit by theft, repair cost inflation, or supply chain disruptions. This variability means earnings exposure depends heavily on each company's book mix, renewal timing, and ability to adjust rates without losing customers to price comparison websites.
Claims Inflation Remains Stubborn
Despite the uptick in premiums, claims costs continue to outpace pricing. The Association of British Insurers (ABI) reported that total payouts reached £2.9 billion in the first quarter of 2026, with £1.9 billion spent on vehicle repairs alone—a 3% increase from the previous quarter. Average accidental damage claims rose 8% to £3,699. ABI director Chris Bose noted, “The sustained high costs of repairs continue to be a concern.”
Confused.com’s own claims data paints an even starker picture. From 2020 to 2025, the average paid-out claim surged 42% from £3,842 to £5,464. Damage claim payouts more than doubled to £4,990, while theft claims jumped 64% to £18,123, and fire payouts nearly doubled to £12,799.
Market Profitability Under Pressure
The combination of rising claims and only modest premium increases is weighing on industry profitability. Oxbow Partners projects that UK motor insurance market profit will fall to approximately £1.3 billion by 2026, down from an estimated £2 billion in 2025, as earned premiums decline while claims costs keep rising. The combined ratio is expected to deteriorate to 95% this year, up from 89% in 2025.
For investors in Admiral Group (LON: ADM), Aviva (LON: AV), and Sabre Insurance Group (LON: SBRE), the key question is whether the pricing floor has been reached before claims inflation is fully tamed. The 2026 earnings season will be a critical test of insurers’ ability to raise rates fast enough to protect margins without losing market share.
Insurer Responses and Outlook
Aviva, which completed its acquisition of Direct Line in July 2025, is now a larger player in a shifting rate environment. In a May trading update, Aviva reported general insurance premiums up 19% to £3.4 billion for the first quarter, with UK and Ireland personal lines jumping 59% thanks to the Direct Line addition. The company reiterated its expectation to keep its UK and Ireland general insurance combined operating ratio under 94% in 2026.
Sabre is taking a more aggressive pricing stance. The motor insurer reported gross written premium up more than 15% to £76.3 million for the first four months of 2026, with motor vehicle premium gaining over 18%. Chief Executive Geoff Carter described gross written premium as “materially ahead of last year” but acknowledged that competition remains intense.
Admiral enters this phase on a high note, having reported UK motor insurance profits exceeding £1 billion in 2025, driven by earlier pricing actions and customer growth. However, the elevated base raises the bar for future performance. If market rates rise only slowly while repair bills stay high, investors will scrutinize how much of Admiral’s profit is cyclical versus sustainable.
Confused.com CEO Steve Dukes warned that the “window is narrowing” for drivers seeking lower prices. For insurers, the window is equally tight: they must raise rates quickly enough to keep pace with repair, credit hire, and parts costs, without driving customers to competitors. The 2026 earnings season will reveal who succeeds.
